A freshly produced sample of a short-lived medical isotope has a measured decay constant of 3.5×10−8s−1. The laboratory needs to state the isotope’s half-life on its safety data sheet.
(a) Calculate the half-life of the isotope in seconds. Show all steps in your work.
(b) Convert the result from part (a) to days.
(c) Convert the result from part (a) to years, expressing your answer using two significant figures.
